No BSOD/memory dump, Random Freezes, Event Log Analysis, Desperate

My kingdom for a resolution! I've troubleshooted everything I can think of. My computer just randomly freezes.

I receive no BSOD either. It just stops responding, the monitor goes dead since it loses signal, yet the computer fans and HD lights continue to run. There is no response from it via mouse or keyboard however. No MEMORY.DMP files are created either.

I disabled automatic restart, so it doesn't reboot at least. Sometimes it freezes when I'm using it, other times in the middle of the night when I'm dead asleep.

To troubleshoot I've:
-Swapped out VGA cards. One seems to produce many more crashes (once or twice a day), but the other still crashes on occassion (once every couple of days) <-- could this be it? why the difference?
-Tested PSU, no problems.
-Reformatted and reinstalled OS
-Did full virus and malware scan with a half dozen different vendors, all came out clean.
-Used CPU temp monitoring software while running Prime95, temps are all fine.
-Ran Memtest overnight on my memory, all passed.
-Updated all drivers and windows updates, including Direct X
-Completely removed all video drivers, did a clean install of video drivers.
-Updated BIOS.
-Completely cleaned PC of dust, made it look brand new, all fans are fine, good ventilation.

The only "hint" I have is the event logs, but after searching the internet for a month on what it means, I'm still stuck. I will post what they say here in the hopes that some kind/smart soul will understand what its pointing at:

There are 2 Errors and 1 Critical in the log each time this happens. First, an error:

Please Help!

Thanks for the reply carwiz.
Smart or not, I appreciate just ANY help right now, any ideas would be good ones.

I checked all the connections, they are all firm and solid with clean pins.
I verified the PSU voltages using HWiNFO64 and also a PSU tester, all voltages were within range and tested fine.

So I'm still clueless.

Anyone? Anyone? Bueller?

The problem is I'm not getting a BSOD. It just freezes and I need to manually restart - most of the time, although I was surprised today to see that it had restarted on its own. No change in the event log though, same exact 3 errors I got as original posted, every time. Still, I don't get a BSOD, and I have my PC to do a full dump (kernel) on system crash, but it still does not produce a memory dump. Should I set it for a mini-dump or something else instead?

I'll set HWiNFO to alert me if the voltages flucuate. What do you think the high and low for that should be? I'm not knowledgeable with voltages, so I dunno if I should put 4 and 6 or more like 4.5 and 5.5, etc. How long should I let the log run for before I post it?

The PSU isn't even 6 months old yet. Here's a cut and paste from NewEgg of the one I have, as I'm not sure which info is most valuable: SeaSonic X Series X-850 (SS-850KM3 Active PFC F3) 850W ATX12V v2.3 / EPS 12V v2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Hi Carwiz,
I appreciate you working with me on this.
I'll do what you said, but I'm trying one more thing first. My OS was on an SSD, and since as far as I can tell there are no real SSD diagnostic programs, I'm now running my OS off a different drive to see if I still get freezes or not. I had reformatted and reinstalled the OS on the SSD drive and that hadn't made a difference, so perhaps it's a drive problem. It's only been running 12 hours so far but I haven't had any freezes, then again I keep having to restart manually as I install programs that I need on a daily basis. If you don't mind, give me maybe a couple days to see if I get any system freezes again, if I do, then it's not a drive issue. If not, then hopefully problem solved. I'll reply as soon as I can confirm if its a drive issue or not. Thanks for all the advice so far, truly appreciate it!

Well, turns out that last little piece of trouble shooting I tried ended up solving the problem. I should have done that before I posted but unfortunately it didn't occur to me until the last minute. There is no way to to a diagnostics test on a SSD drive, not that will tell you there are any subtle problems that is, so I had to send an email to Crucial (manufacturer of the drive) explaining the problem that I stated above. This was there response:
____________
Thank you for contacting us. The behavior you are describing is consistent with TRIM commands not executing on the drive (which may result from lots of writing and rewriting, especially OS installs, not done on the OS level, and which can be blocked by a SATA controller running in IDE mode as you've indicated). The accumulation of 'junk' data from file deletions, even reformats, basically clogs up the drive and reduces or sometimes even halts performance and can even dismount the drive. A secondary feature called Garbage Collection activates when the drive is powered, but has no data throughput, for an extended period, and does background cleanup on our SSDs which can make up for the lack of TRIM.

If this is the cause of your drive's behavior, a period of idling the drive without any data being written or read actively will improve its performance. We recommend you perform this idle period on a desktop computer because it allows you to only connect the SATA power connection.
_____________
I did what they asked, ran it idle for about 12 hours, and then booted off it again. I'm now on day four of constant uptime, which I haven't been able to do for about two months, so that definitely solved the problem. I'm also thankful I don't have to buy any replacement PC components, ha. Anyway, just wanted to anywho who sees this know, perhaps this can help them in the future. I searched google for a month on this problem and found nothing. Hope this can help others. I appreciate your help as well carwiz. Until next time.

Ha, thanks... but... wow, this is embarrassing... the problem still exists. Same thing as before, nothing changed except frequency of crashing now. Listening to the Crucial tech did seem to help, as like I said, I got a world more of uptime than I previously had. Hopefully that points to it really being an HD problem though and nothing else. I sent an email to crucial telling them it still happened, as their previous email said IF the "garbage cleaning" didn't work than it may be up for a warranty exchange. Hopefully if and after that happens, assuming it doesn't crash, I can say with 100% confidence that it was really the HD. Now all possibilities still exist. But at least I'm not out of options, as I'm still working with Crucial on the drive problem. Anyway, again, thanks a ton carwiz (for the rep too), I'll update this thread once I can confirm the problem (assuming I can).
